You should ask the R-CAR maintainers first to have a look at your code and ACK accordingly. Lorenzo

This patch series adds support for PCIe controller on rcar to work in endpoint mode, this also extends the epf framework to handle base region for mapping PCI address locally. Note: The cadence/rockchip/designware endpoint drivers are build tested only. Changes for v5: 1] Rebased the patches on next branch of https://git.kernel.org/pub/scm/ linux/kernel/git/helgaas/pci.git 2] Fixed review comments reported by Kishon while fetching the matching window in function pci_epc_get_matching_window() 3] Fixed review comments reported by Bjorn a] Split patch up first patch so that its easier to review and incremental b] Fixed typos 4] Included Reviewed tag from Rob for the dt-binding patch 5] Fixed issue reported by Nathan for assigning variable to itself Changes for v4: 1] Fixed dtb_check error reported by Rob 2] Fixed review comments reported by Kishon a] Dropped pci_epc_find_best_fit_window() b] Fixed initializing mem ptr in __pci_epc_mem_init() c] Dropped map_size from pci_epc_mem_window structure Changes for v3: 1] Fixed review comments from Bjorn and Kishon. 3] Converted to DT schema Changes for v2: 1] Fixed review comments from Biju for dt-bindings to include an example for a tested platform. 2] Fixed review comments from Kishon to extend the features of outbound regions in epf framework. 3] Added support to parse outbound-ranges in OF.
